RESUMO
Objectives: Hypotensive anesthesia is necessary during endoscopic sinus surgery to achieve a bloodless surgical field. The aim of this study was to compare the quality of surgical field using propofol or desflurane anesthesia
Methodology: 40 patients of either sex, belonging to ASA physical status I and II, and age group of 18 - 60 years were randomized into two groups to receive either propofol and morphine or desflurane and morphine anesthesia. The target mean arterial pressure [MAP] was kept in a range of 65-75 mmHg. The quality of surgical field was assessed by using a validated scoring system [Fromme category scale] at every 15 min by the same surgeon in all the cases to avoid surgeon's bias
Results: The mean category scale value was 2.665 +/- 0.243 in propofol group and 2.200 +/- 0.410 in desflurane group [p=0.000]. The time to emergence was significantly less in desflurane group [9.35 +/- 1.27] as compared to propofol group [14.60 +/- 2.06 min]
Conclusion: We conclude that both the propofol and desflurane can be used to achieve a satisfactory surgical field quality but desflurane provides a rapid emergence as compared to propofol
RESUMO
Laryngeal mask [LM] airway is commonly used for securing airway in day-care surgeries. Various problems have been described while using LM airway. Out of those, mechanical obstruction causing airway compromise is most common. Here, we describe a case report of 4-year-old child who had partial upper airway obstruction due to LM manufacturer's defect. There was a silicon band in upper one-third of shaft of LM airway. This band was made up of the same material as that of LM airway so it was not identifiable on external inspection of transparent shaft. We suggest that such as non-transparent laryngeal mask, a transparent LM airway should also be inspected looking inside the lumen with naked eyes or by using a probe to rule out any manufacturing defect before its insertion
